Comparison
215/50 R17 vs 225/60 R16
Going from 215/50 R17 to 225/60 R16 is a minus-1 setup that adds sidewall on a smaller 16-inch wheel. This sizing approach moves rolling diameter well outside the usual OEM tolerance.
The speedometer error is noticeable and may warrant a recalibration if you rely on indicated speed. More sidewall typically improves comfort and curb protection, especially on city streets. Extra width broadens the footprint for more grip, but check inner liner and strut clearance before fitting. Minus-sizing keeps replacement costs down and opens up a wider range of winter and all-terrain tires. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
TakePractical direction for winter wheels, chains, or rougher pavement where cushioning matters.
Quick math: 225/60 R16 is 29.6 mm taller than 215/50 R17, shifting the speedometer by +4.58%.

Speedometer impact
At a true 100 km/h, your dashboard will read 104.6 km/h after switching to 225/60 R16 — a +4.58% offset. Use the speedometer error calculator to recheck for other indicated speeds, and the speedometer error guide for the full background.
Ground clearance change
The new tire's half-diameter changes ride height by +14.8 mm. Small differences are absorbed by suspension travel, but anything beyond ±10 mm can affect headlight aim, fender clearance and bump-stop margin. See the plus-sizing guide before committing.
